The APR script uses this as a "gate" to +clear ac_cv_file__dev_zero when /dev/zero exists but it turns out not +to be useable. They take a pessimistic approach: if you can't "prove" +it is mmap-able, clear the flag. + +This patch changes that to leave the flag alone while cross compiling; +just assume /dev/zero is mmap-able.
